Randomized, Controlled Trial of Topical Exit-Site
Application of Honey (Medihoney) versus
Mupirocin for the
Prevention of Catheter-Associated Infections in Hemodialysis
Patients

David Wayne Johnson, Carolyn van Eps, David William Mudge, Kathryn Joan Wiggins,Kirsty Armstrong, Carmel Mary Hawley, Scott Bryan Campbell, Nicole Maree Isbel,Graeme Robert Nimmo, and Harry GibbsDepartment of Renal Medicine, University of Queensland at Princess Alexandra Hospital, Brisbane, Australia The clinical usefulness of hemodialysis catheters is limited by increased infectious morbidity and mortality. Topical antiseptic
agents, such as mupirocin, are effective at reducing this risk but have been reported to select for antibiotic-resistant strains.
The aim of the present study was to determine the efficacy and the safety of exit-site application of a standardized antibacterial
honey versus
mupirocin in preventing catheter-associated infections. A randomized, controlled trial was performed comparing
the effect of thrice-weekly exit-site application of Medihoney versus
mupirocin on infection rates in patients who were
receiving hemodialysis via tunneled, cuffed central venous catheters. A total of 101 patients were enrolled. The incidences of
catheter-associated bacteremias in honey-treated (n
؍ 51) and mupirocin-treated (n ؍ 50) patients were comparable (0.97 versus
0.85 episodes per 1000 catheter-days, respectively; NS). On Cox proportional hazards model analysis, the use of honey was not
significantly associated with bacteremia-free survival (unadjusted hazard ratio, 0.94; 95% confidence interval, 0.27 to 3.24; P
؍
0.92). No exit-site infections occurred. During the study period, 2% of staphylococcal isolates within the hospital were
mupirocin resistant. Thrice-weekly application of standardized antibacterial honey to hemodialysis catheter exit sites was
safe, cheap, and effective and resulted in a comparable rate of catheter-associated infection to that obtained with mupirocin
(although the study was not adequately powered to assess therapeutic equivalence). The effectiveness of honey against
antibiotic-resistant microorganisms and its low likelihood of selecting for further resistant strains suggest that this agent may
represent a satisfactory alternative means of chemoprophylaxis in patients with central venous catheters.

The potential weaknesses of this trial were its open-label design, the possibility of type 2 statistical error, and the lack ofstatistical power to confirm therapeutic equivalence of honeyand mupirocin. The absence of blinding could have potentiallyintroduced co-intervention and observer biases. For example,Wagman et al. (42) showed an eightfold higher rate of infectionsassociated with tunneled, cuffed catheters that were managedoutside study protocol compared with those that were man-aged using the technique required by the study. Such protocoldeviations were strictly avoided in the present study by ensur-ing that nursing staff adhered to a standardized exit-site careprotocol and carefully documented their actions at each dress-ing change. Moreover, observer bias was minimized by the useof clearly defined, objective outcome measures and by blindingto the patient’s study group assignment the microbiology lab-oratory staff who processed culture samples. As stated in theMaterials and Methods section, the study was adequately pow-ered to have detected a halving (or doubling) of risk in thehoney arm compared with the mupirocin arm.
